Guilt and sorrow are SO associated with Alcohol. I know... Don't let them get to as long as you are making an effort to eliminate them. And there's only one way to do that. Tell yourself you're sick of feeling sad, down, ashamed, etc. and make positive changes.
If you can allow yourself to be stubborn about that ONE thing in your life, for the rest of your life, you can pull this off. It took me a DUI to convince myself that I was worthy of more than disappointment, shame and anguish, along with hang-overs, foolish behavior etc. Tomorrow will be 9 months since I allowed alcohol in my mouth. It can be done.
Chin up and move forward, one single day at a time. And spoil yourself with all the love you want. We're all worth it!
